New York City FC signed Peru international defender Alexander Callens from Spanish club Numancia on Friday.
Callens, 24, has played in Spain for the past six seasons, spending four years with Real Sociedad's reserves before moving to second-tier Numancia.
The center-back moves to MLS on a free transfer.
"I'm really happy to welcome Alexander to the squad. He's an international defender with the characteristics we look for in his position," NYCFC coach Patrick Vieira said in a statement.
